Many years ago I went to an airshow in the Northern Hemisphere.
There was a Herc on static display. Towbar attached.
As we left said show, the Herc passed overhead with gear down and said towbar still attached - albeit not pointing forwards.
It then flew by the tower with gear up and no towbar.
Presume it didn't fall off anywhere important.
If the crew would like to buy me a coffee, I'll be at the same show this year!
